UPFC MODELLING THESIS

Series converterprovides the main portion of the UPFC by injecting a voltage with controllable magnitude andphase angle in series with the cable. Three modern controllers have been designed and tested for controlling the UPFC in a power flow mode for the series part and a voltage control mode for the shunt part. Farther, this intelligentmethod proved to be more beneficial than existing traditional methods such as PSS. The output membership function also consists of triangular membership function and rules described in Fig. The synchronous generator is represented by model 1, i.

The third controller is designed using the adaptive capabilities of neural networks to estimate and tune the fuzzy rules. Currently, he has worked at the Sadjad Institute for Higher Education. Power flow is the analysis to determine the steady-state magnitude and angle voltages at all buses of the power system and also the real and reactive power flows in every transmission line. In this network active and reactive power of buses load 9, 10 and 14 are changed.

Power flow is the analysis to determine the steady-state magnitude and angle voltages at all buses of the power system and also the real thesus reactive power flows in every transmission line.

Active power losses MW. Using this model, two virtual buses are added to the network. In thfsis law to providing stabilizer signal, the output of obtained model reference ofpower system is compared with output of the actual power system and the error signal is fed to afuzzy controller.

In this network active and reactive power of buses load 9, 10 and 14 are changed. The UPFC parameters in order to increase voltage level and decrease power losses are adjusted. Test results using different power system thesia are presented throughout the thesis to illustrate the effectiveness of Unified Power Flow Controller.

The shunt converter isutilized applied to apply the active power demand of the series converter through the commonDC link. The value of injected voltage angle.

Load flow studies with UPFC power injection model – ethesis

The application ofCPSS for the advance of small signal oscillation and the dynamic stability of a power system hasbeen excused in the literature [2]. The influence of both the ufc and shunt inverters on this controlled area has been analysed.

Computer simulation and experimental implementation of a UPFC using DS data acquisition board have been used to verify the proposed control strategies.

Wash out This block consists of two wash-out filters with time constant 10second. In this case UPFC can be modeled by a load at the sending bus PQ bus, satisfy the equations 4 and 5 and an “equivalent PQ generator” at the receiving bus PQ bus, satisfy the equations 6 and 7.
